GR8387

Secondary Side Synchronous Rectifier Controller

Features

Description

GR8387 is the synchronous rectifier controller

used in discontinuous conduction mode and

quasi-resonant flyback converters. The IC controls

N-MOSFET to substitute Schottky diode. The VD

to VS voltage difference is sensed to decide the

polarity of the current and turn the power switch

on/off in nearly of zero current transition. When

light load the gate driver output can be disable to

avoid long MOSFET turn on period.

High speed secondary synchronous rectifier

High system efficiency from no load to full load

Light load protection function

DCM topology

200V high voltage technology

Ultra low startup and quiescent current

Vcc ranges from 11.6V to 19.5V

SOP-8 green (Halogen free) package

Applications

ATX power supply

NB adapter

LCD TV

SMPS
